Ceva Adaptil diffuser and 48 ml vial is a product for normalising dogs' behaviour in stressful situations. The manufacturer calls it an effective and safe way to restore your pet's wellbeing. Under stress a dog may howl or bark for hours, chew and destroy things, soil indoors and lick itself excessively. Adaptil reproduces the pheromone that nursing bitches release 3–5 days after giving birth: it gives puppies a sense of calm and connection with their mother, and according to the manufacturer dogs remain receptive to it throughout life. The set includes a diffuser and a 48 ml vial.
How to set it up
Remove the cap from the vial, insert the vial into the diffuser and screw it in until you feel slight resistance, then plug the assembled diffuser into a socket. Place it in the room where your dog spends most of its time. The diffuser works on 110–240 V and covers 50–70 m². It must not be used with a multi-socket, extension lead or adapter. It should run continuously for 4 weeks, and the vial is replaced as needed.

Pros
- Works without your involvement. Plug it in and forget it for a month.
- Safe. For dogs, people, puppies, seniors, and pregnant or nursing dogs.
- Compatible with medication. Can be combined with veterinary treatments.

- No smell for people. The pheromone is meant for dogs.
Cons and what to watch
- Not instant. The diffuser must run continuously, and the effect builds gradually.
- Needs a wall socket. No multi-sockets or extension leads, which is not always convenient.
- Does not solve everything. Severe anxiety needs training and sometimes medication.
- Dogs only. Cats have different pheromone products.
When to use it
The manufacturer lists the situations: early weaning, fear of noises such as fireworks, thunder and gunshots, separation from the owner and fear of being alone, a new family member, vet visits, shows and travel. It is best to switch the diffuser on in advance — a few days before fireworks or a move — so the pheromone has time to fill the room.
Diffuser, spray or collar
Adaptil comes in three forms. The diffuser works indoors and suits stress linked to the home: noise outside, being alone, a new household member. Adaptil spray is handy for treating a carrier or bedding before a trip, and the Adaptil collar stays with your dog on walks and journeys. They can be combined.
A combined approach
The pheromone lowers anxiety but does not teach a dog new behaviour. For separation anxiety, gradual training, puzzle toys and enough exercise before you leave help. For panic during fireworks, a safe "den" with a bed helps. More options are covered in calming products for dogs and cats. If your dog injures itself or wrecks the home, consult a vet or a dog trainer.
For a puppy in a new home
Leaving its mother and littermates is a puppy's first big stress. A diffuser switched on in the room with its bed helps the puppy settle faster and whine less at night. What else to prepare for a new puppy is covered in a puppy at home: shopping list.
Device safety
Plug the diffuser directly into a wall socket only, do not cover it with furniture or curtains and keep it out of reach of your dog and children. Do not place it behind a sofa or in an alcove without air circulation, as the pheromone will spread less well.
Who it suits
The diffuser suits dogs that fear noise, cope badly with being alone, are stressed by a move or a new family member, and puppies in their first weeks at home. Other products are in our calming products for dogs collection and the vet pharmacy section.
Verdict
The Ceva Adaptil diffuser with a 48 ml vial is a calming pheromone product for dogs: it covers 50–70 m² indoors, runs continuously for 4 weeks and is safe for puppies, seniors and pregnant or nursing dogs. The downsides are the gradual effect, the ban on extension leads and the fact that a diffuser alone is not enough for severe anxiety.
